3.Soon enough,we will lose some of the most amazing sites on Earth!The Great Barrier Reef---Rising air temperatures will cause sea temperatures to rise as well.All life supported by the oceans will be affected with this shock to their ecosystem.Coral are some of the most vulnerable marine animals and we are already watching whole reefs disappear.The Great Barrier Reef in Australia is no exception and will continue to shrink as the temperatures rise!These reefs are some of the best in the world for diving,but they will soon disappear!
Venice---Sprawing across(橫跨)hundreds of small islands in Northeast Italy,Venice is at extreme risk of sinking into the Adriatic Sea.Rising sea levels are in fact a serious threat to many coastal cities located at sea level.Lucky for us,however,Venice is developing a series of sea walls to protect the city in times of high tide.
Glacier(冰川)National Park---Glacier National Park was once covered by over 150glaciers,but by 2005it only had about 27!Located in Montana,Canada,this park is over a million acres and has a huge plant and wildlife population.As temperatures rise,the glaciers and ice melt,which will upset the ecosystems sustaining over a thousand plant species and hundreds of animals.
The Amazon---The cause behind the disappearance of these fantastic places ultimately comes down to humans.Our expansion usually requires cutting down forests for land,fuel and materials,but rarely considers the consequences.These forests are sources of food and medicine for just about everyone on the planet!
What will happen if we lose these valuable places and beautiful destinations?!

分析 本文講述了我們正在失去一些地球上驚奇的景觀,而造成這一現(xiàn)狀的原因是氣溫上升引起的海平面升高以及人類的破壞環(huán)境.
解答 8.C.細(xì)節(jié)理解題.由第一段The Great Barrier Reef---Rising air temperatures will cause sea temperatures to rise as well.All life supported by the oceans will be affected with this shock to their ecosystem可知海水溫度上升影響了生態(tài)系統(tǒng),導(dǎo)致了珊瑚蟲死亡,故選C.
9.B.細(xì)節(jié)理解題.由第二段Rising sea levels are in fact a serious threat to many coastal cities located at sea level可知海平面上升對(duì)許多位于海平面的沿海城市來說是一個(gè)嚴(yán)重的威脅,故選B.
10.A.細(xì)節(jié)理解題.由第三段Located in Montana,Canada,this park is over a million acres and has a huge plant and wildlife population,可知冰川自然公園在蒙大拿州占據(jù)很大的面積,故選A.
11.D.細(xì)節(jié)理解題.由最后一段Our expansion usually requires cutting down forests for land,fuel and materials可知,亞馬遜雨林的縮小是因?yàn)槿祟悢U(kuò)張土地,砍伐森林獲取材料,而其他三個(gè)都是由于氣候變暖,故選D.
點(diǎn)評(píng) 本篇文章都是細(xì)節(jié)推理題,答題的已給選項(xiàng)也一般不會(huì)和短文相關(guān)詞語(yǔ)完全相同,需要考生自己理解句子,延伸推理出題目答案,比一般細(xì)節(jié)理解題偏難.
